Immunity to Magic (Ex) A force golem is immune to any spell or spell-like ability that allows spell resistance, with the exception of disintegrate spells or spell-like abilities, which affect it normally.

Vulnerability to Disjunction (Ex) A force golem touched by a rod of cancellation as a melee touch attack or caught within the area of a mage's dinjunction spell is affected as if it had been successfully hit with a disintegrate spell of the same caster level. Whenever a rod of cancellation damages a force golem in this manner, the rod crumbles to dust.

Construction

A force golem is not constructed from a physical body, instead being generated by special ritual components worth no less than 100,000 gp, all of which are consumed during the golem's creation. A prismatic golem instead requires components worth 200,000 gp, and requires a prismatic wall spell instead of a wall of force spell.

Force golems are made not of matter, but of pure magical force. Unlike some force effects, force golems are visible, though translucent. Despite their ephemeral appearance, force golems are harder than adamantine, and can deliver devastating blows of pure force.

A force golem is 16 feet tall and effectively weighs 4,000 pounds. (Technically, a force golem has no mass; its weight and inertia result from pure force with no physical source.)

Prismatic Golem (CR +1) A prismatic golem is a force golem that glows with all seven colors of the rainbow, sheding light as if it were a sunrod. Prismatic golems are immune to disintegrate spells (and don't gain vulnerability to disjuction), but can be destroyed by spells, color by color, in the same manner as a prismatic wall. A prismatic golem is created using a prismatic wall spell instead of a wall of force spell, and its creation requires ritual components worth twice as much as those used in the construction of a standard force golem.
